Background and Objective: the researchers are seeking to find ways to more effectively offer the educational programs to the university students. There are numerous advantages in delivering the instructional material by way of educational films. The present study aims at investigating the effect of displaying films before craniotomy surgery on self-efficacy and stress in operating room technology students in Isfahan’s selected educational hospitals.
Materials and Methods: Fifty operating room MA students from semesters 4, 6 and 8 were stochastically assigned to two test and control groups in the current randomized two-staged (before and after) clinical trial research with evidence group. Craniotomy surgery films were displayed for the test group before the onset of operation and the control group was given the routine instructions. Data collection instrument was comprised of two researcher-constructed questionnaires which were based upon the standard perceived stress scale (PSS) and self-efficacy questionnaire by Sherer. Both of the questionnaires underwent reliability and validity tests and they were put into use after they were confirmed. The data were analyzed by means of SPSS 16 through taking advantage of descriptive and analytical tests in a 0.05 significance level.
Findings: the results indicated that the pre-intervention perceived stress mean scores of the two test and control groups are not reflective of a significant difference (P>0.05). Also, the pre-intervention self-efficacy mean scores of the two test and control group was not suggestive of a significant difference (P>0.05). Post-intervention perceived stress mean score in test group was found significantly lower than the control group. Furthermore, post-intervention self-efficacy mean score was found significantly higher in test group than the control group (P<0.05).
